ンパ。 A damper casing connected between the ducts, a blade rotatably supported inside the damper casing, a closing mechanism that rotationally drives the blade to close between the ducts, and a closing mechanism provided inside the damper casing. In the fire prevention damper, the closing mechanism includes a temperature fuse device that detects a temperature rise and operates at a temperature higher than a set temperature, and a drive means that adjusts the opening degree of the blades via a deceleration mechanism when the duct is in use. The clutch mechanism includes a clutch mechanism that blocks transmission of axial force from the drive means when the clutch mechanism is activated, a spring that rotates the blade in the closing direction when the clutch mechanism is activated, and a latch mechanism that maintains the activated state of the clutch mechanism. A fire damper characterized by:
